Abstract (en)
[origin: CA2108691A1] An injection device is disclosed, into which an ampule with a piston and an injection needle may be interchangeably set. It has an actuating arrangement essentially composed of an operating knob, a driving element, a guiding element and a driven member, preferably having a rod and a flange. The driven member is rotatably secured to the guiding element fixedly arranged in the device and seats with its thread in a female thread of the driving element that can be axially moved and twisted by manually operating the operating knob. When the operating knob is twisted, the driven element is moved forward and pushes the piston forward during the following axial displacement, so that injection is the result. In the disclosed device, the fixed guiding element is located before that axially movable driving element. The length of the operating arrangement is therefore shorter than in state-of-the-art injection devices, so that a larger axial dosis may be injected with a device having the same overall length. This device is useful for medical applications.
